Lately, I find myself looking for the github icon before anything else in a website. I find a github readme much more readable than any landing website.
The first two sentences of the readme are:
> Syncthing is a continuous file synchronization program. It synchronizes files between two or more computers.
That copy should absolutely be somewhere on the main website.
Yes. Specifically, it should be in a large font, roughly centered, at the top of the page. You should load the page, and immediately read those words.
